The world's population is increasingly becoming urbanized. If the current urban growth rate is to continue, new and unprecedented challenges for food security will be inevitable. Dietary diversity has been used to ascertain food security status albeit at the multicountry and country levels. Thus, household-level studies in urban settings, particularly in sub-Sahara African, are few. Yet, it is imperative that assessments of food security are undertaken particularly in urban settings, due to the projected fast rate of urbanization and the challenges of attaining food security.
To examine household characteristics and dietary diversity.
The study uses data from 452 households from the second round of the Regional Institute for Population Studies (RIPS) EDULINK urban poverty and health study. Bivariate and multivariate analyses are undertaken.
Mean dietary diversity for all households is 6.8. Vegetables have the highest diversity, followed by cereal-based and grain products. Household characteristics that have statistically significant associations with dietary diversity include sex and level of education of household head, household wealth quintile, and source of food.
There is high dietary diversity in the study communities of Accra but low consumption of foods rich in micronutrient, such as fruits and milk/dairy products. The study brings to fore issues related to resource-disadvantaged entities of the urban system, namely, females, poor households, and the non-educated who have food insecurity problems.
世界人口正日益城市化。如果当前的城市增长率持续下去，粮食安全将不可避免地面临新的、前所未有的挑战。饮食多样性已被用于确定多国和国家层面的粮食安全状况。然而，在城市环境中，尤其是撒哈拉以南非洲地区的家庭层面研究却很少。鉴于预计的快速城市化进程以及实现粮食安全所面临的挑战，在城市环境中进行粮食安全评估势在必行。
研究家庭特征与饮食多样性。
本研究使用了区域人口研究所在第二轮“教育联系”城市贫困与健康研究中收集的452个家庭的数据，并进行了双变量和多变量分析。
所有家庭的平均饮食多样性为6.8。蔬菜的多样性最高，其次是谷类和谷物制品。与饮食多样性具有统计学显著关联的家庭特征包括户主的性别和教育程度、家庭财富五分位数以及食物来源。
阿克拉的研究社区饮食多样性较高，但富含微量营养素的食物，如水果和牛奶/乳制品的消费量较低。该研究凸显了城市系统中资源劣势群体，即女性、贫困家庭和未受过教育者所面临的粮食不安全问题。
